' a simply Application filed January 20 Specification of Letters Patent.

Patented Aug. '26, 1913. 1912. Serial 1%. man.

To all whom it may concern:

Be it known that I, JONAS P. JENsEN, a citizen of the United States, anda resident of Silver Beach, in the county of 'Wha'tcoin, in the State oflVashington, have invented new and useful Improvements in Saw-Handles,of which the following is a specification.

This invention relates to improvements in saw handles.

The object of the invention is to provide constructed handle havingreliable means for engaging the edge of the rear end of a saw blade.

Another object is to provide jaws for en gaging opposite faces of a sawblade, said jaws being adjustable to adapt them for use on saws havingtransversely spaced apertures arranged at Varying distances apart.

WVith these and other objects in view, the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

I11 the accompanying drawings: Figure 1 represents a side elevation of asaw handle constructed in accordance with this inven tion applied, aportion of the saw blade being broken off; Fig. 2 is a top plan Viewthereof.

In the embodiment illustrated blade clamping jaws 1 and 2 are shown, oneof which is fixed and the other movable and both of which are providedwith semi-circular portions 3 and 4 arranged intermediately of theirends and positioned opposite each other when the jaws are in closed oroperative position, forming an annular member into which the rear end ofa saw blade B is designed to extend and in which is mounted an eccentriclongitudinally corrugated or grooved blade holding member 5. This holder5 is secured to the movable jaw 2 and moves with said jaw to engage withor disengage from the corrugated seats the rear edge of the saw blade B.

The free ends of the jaws 1 and 2 are provided respectively with studs 7and apertures 8, the studs 7 on the jaw 1 being positioned to projectthrough the apertures 8 when the jaws are closed. The blade B isprovided at its rear end with transversely spaced apertures 9 positionedto aline with the studs 7 when the parts are in operative position andthrough which said studs pass I and engage the apertures 8 of the otherjaw Simultaneously with the closing of the jaw 2 the blade locking orholding member 5QSWiI1gS 111170 engagement with the real edge {of bladeB, one of the seats of said member 5 receiving said blade edge. The rearend of the movable jaw 2 has teeth 10 with which are designed to beengaged a locking dog 11 for securing the jaw in closed position and inclamping engagement with the blade B.

As shown each jaw comprises two members or arms 12 and 13 mounted on abolt 14 having threaded ends in threaded engagement with the jawmembers, whereby said members may be adjusted toward or away from eachother to position the studs and the apertures thereof for engagementwith saw blades having apertures spaced different distances apart. Thehand grip 15 0f the handle is arranged between the members of the jawsand adjacent to which the locking dogs 11 are mounted.

While I have described my invention with more or less minuteness asregards details and as being embodied in certain precise forms, I do notdesire to be limited thereto unduly any more than is pointed out in theclaims. On the contrary, I contemplate all proper changes in form,construction and arrangement, the omission of immaterial elements andsubstitution of equivalents as circumstances may suggest or renderexpedient.

I claim as my invention.

1. A saw handle comprising a plurality of members pivoted to swingtoward and away from each other, blade engaging jaws carried by saidmembers and having means for locking engagement with a saw blade andblade holding means carried by one of said members and movable therewithfor engaging the blade when the member is swung into closed position andfor releasing it when said member is opened.

2. A saw handle comprising a pair of members pivoted to swing toward andaway from each other, said members having clamping jaws for engagingopposite faces of the saw blade, and a corrugated member carried by oneof said members for engaging the rear edge of a saw blade and holding itfirmly in position.

3. A saw handle comprising pivotally connected members having means forclamping a saw blade and a longitudinally corrugated element carried byone of said members for engaging the rear edge of the saW blade to holdit firmly in operative position.

4. A saw handle comprising pivotally connected members having clampingmeans for engaging a saw blade, one of said members being provided Withteeth, and a locking dog for engaging said toothed member 10 for holdmgit 111 closed positlon.

5. A saw handle comprising pivotally connected jaws, an eccentriccarried by one JONAS P. JENSEN.
